OBJECTIVES The aim of this study was to compare the effects of certain commercially available mouthwashes on cariogenic bacteria and biofilms, following the acquisition of inhibition potentials of caries. MATERIALS AND METHODS Mouthwashes containing I) chlorhexidine gluconate (CHG; 0.0005% w/v), II) benzethonium chloride (BTC; 0.01% w/v), III) an essential oil (Listerine), and IV) povidone-io...

the role of polymeric additives such as pvp and peg is studied with respect to the morphology of pes porous layer as a sublayer of nanofiltration composite membranes based on pes/pa. results show that by phase inversionprocess of quaternary systems comprised of four components of polymer/solvent/non-solvent/additive and the diffusion of intertwined polymers some changes occur in membrane morpho...

to improve the corrosion protection of copper metal, 0.01m concentration of 1h-1,2,4-triazole-3-thiol (tat) was incorporated into the hybrid sol-gel monolayers containing 3-glycidoxypropyltrimethoxysilane (gptms) and tetraethoxysilane (teos). it was further subjected to hydrolysis and condensation reaction to form a sol-gel matrix. the tat-doped hybrid sol-gel coating was applied over the coppe...

introduction: green light photo selective vaporization of the prostate (pvp) is a minimally invasive method of treatment for clinical benign prostatic hyperplasia with fewer side effects. the aim of this study is to evaluate the safety, effectiveness and cost analysis of pvp compared with transurethral resection of prostate. methods: a systematic search was done in cochrane, trip database, medl...

A mixture of copper complex and Al/CuO nanothermite, Al/CuO/CuC, represents one the state-of-the-art gas-generating thermite systems with various pyrotechnic applications due to its tunable gas release rates. The reactivity reactive inks loadings poly(vinylpyrrolidone) (PVP) binder mixed Al/CuO/CuC is characterized using high-speed imaging diagnostics pressure measurements. For a PVP mass fract...

OBJECTIVES Report the incidence and structure of testicular appendices (TAs) in patients with cryptorchidism, comparing their incidence with epididymal anomalies (EA) and patency of the vaginal process (PVP) and analyzes the structure of TAs. MATERIAL AND METHODS We studied 72 testes of patients with cryptorchidism (average of 6 years), and 8 testes from patients with hydroceles (average of 9...

T cells from CAF1 mice immunized with various amounts of the type 2 antigen polyvinylpyrrolidone (PVP) were assessed for their ability to provide help to PVP-specific memory B cells for the production of IgG. Low doses (0.0025 micrograms) of PVP consistently activated helper T cells (Th), which were required for the production of IgG by primed B cells. In contrast, T cells from mice primed with...

Metal–organic frameworks (MOFs) featuring porous structures and large specific surface areas have shown great potential in removing organic pollutants from wastewater via adsorption processes. Although the particle size of MOFs determines performance (something known as size-dependent effect), engineering it into desirable dimensions for enhancing is a challenge. Here, we develop practical faci...
